My invention relates to improvements in elevat
the rear ends of the sides and the top of the body
I3. The side ñanges of the channel bar I5 are
turned inwardly relative to the plane of said
channel bar. The legs of the channel bar l5 af
ford a pair of fixed upright tracks I6 and the
transverse portion of said channel bar affords a
cross-tie for the tracks IE at their upper ends.
An end gate Il for the end gate opening I4
is carried by a pair of upright movable tracks I8.
These movable tracks I8 are in the form of chan
nel bars positioned between the fixed tracks I6
and in the same vertical plane. The side flanges
of the movable tracks I8 extend toward the side
flanges of the ñxed tracks I6. By reference to
Figs. 5, 6 and 7 it will be noted that the movable
tracks I8 are narrower than the ñxed tracks I6
and that the outer side ilanges of said tracks are
flush.
ing gates for vans and other vehicles.
The object of this invention is to facilitate the
loading and unloading of vans and other vehicles
and the opening and closing of the gates thereof.
To the above end the invention consists of the
novel devices and combination of devices herein
after described and defined in the claims.
In the accompanying drawings, which illustrate
the invention, like characters indicate like parts
throughout the several views.
Referring to the drawings:
